After Kaan joined the New Sith Empire, becoming the Dark Lord of the Sith, LaTor was one of the Sith that claimed the title of Dark Lord and waging endless campaigns against each other, rather than uniting to bring down the Galactic Republic and the Jedi Order. Lord Skere Kaan stepped in to their vanity, and named them all Dark Lords of the Sith. After Kaan became the founder of the Brotherhood of Darkness, LaTor pledged himself to his cause, along with Qordis and Kopecz, warlords of the Sith. With his charisma and power, LaTor and the Sith struck back against the Republic and the Jedi. Thousands of Sith and Jedi battled one another across the galaxy, and LaTor became the fifth ranked Sith Lord of the Brotherhood of Darkness. As long as the victories continued, LaTor and the Sith would remain united behind Lord Kaan.

During the Seventh Battle of Ruusan, he was very knowledgeable in the dark arts and helped Kaan develop the thought bomb. While LaTor and the Sith masters were guarding, Army of Light attacked and battled against the Sith while Kaan waited for the Jedi and the Sith's final strike. Under Kaan's guidance, LaTor and the rest of the Sith they would be strong enough to survive the thought bombs effect and it it would only kill the Jedi. As the Sith confronted the Jedi inside the Deep Caves, LaTor was killed when the thought bomb was detonated in the battle. His spirit was trapped in this Force prison, along with all the Jedi and the Sith. LaTor thought that the bomb would only kill the Jedi, but he came to realize that Kaan deceived him and the Sith, and would never survive the final campaign. LaTor possibly abandoned the dark side, and took his step to the light while he remained in the prison.
